IPC: H03H9/25
Filed: 1989-10-11
Abstract: PURPOSE:To miniaturize the size of the device small and to facilitate the adjustment of attenuation by arranging a resistor connected between an input terminal and an output terminal onto a same piezoelectric substrate as a 2-port surface acoustic wave resonator after applying circuit integration to the resistor. CONSTITUTION:A resistive element 16 is formed on a same piezoelectric substrate 11 provided with a lateral mode resonance 2-port surface acoustic wave resonator comprising interdigital electrodes 12, 13 and reflectors 14, 15. The resistive element 16 is a resistor of meander line state metallic thin film such as an aluminum thin film forming a surface acoustic wave element or a resistor made of a carbon by sputtering or the like.
